Air-Purifying Elements 4 PA3ISBU Air-Purifying Elements Principle of Operation The following filter/cartridge protection classification applies when used with any of the hoods or loose fitting facepieces. In the following table “Quantity” refers to the number of filters/cartridges which must be attached to the blower unit to provide the required protection. Protection Filter/Cartridge Type Quantity NIOSH / ANSI Color Code for Cartridge Label HE PAPRFC1 2 Purple OV/CL/HC/SD/CD/HF/HE PAPRFC2 3 Yellow and Purple CL/HC/SD/CD/HF/FM/AM/MA/HE PA3NBC* 3 Olive Green and Purple * The PA3NBC cartridge provides protection for acid gases, formaldehyde, and ammonia and therefore is effective against a wide range of Toxic Industrial Chemicals. The High Efficiency (HE) Particulate Filter provides protection against airborne bacteria, viruses, and other particulates. Although not NIOSH-approved for use against the following contaminants, independent laboratories have tested and verified that the PA3NBC cartridge is effective against many chemical warfare agents and/or their recognized surrogates. These agents/surrogates are listed below. PA3NBC CARTRIDGE CHEMICAL WARFARE GAS PERFORMANCE TESTING Gas Challenge Test Flow Breakthrough Time to Concentration Rate Concentration Breakthrough DMMP 3000 mg/m3 50 lpm .04 mg/m3 >120 minutes* Sarin (GB) 4000 mg/m3 32 lpm .04 mg/m3 >120 minutes* Cyanogen Chloride (CK) 4000 mg/m3 32 lpm 8.0 mg/m3 30 minutes* Chloropicrin (PS) 15000 mg/m3 30 lpm 0.7 mg/m3 60 minutes Hydrogen Cyanide (AC) 5500 mg/m3 30 lpm 5.0 mg/m3 >30 minutes Tear Gas (CS) 23 mg/m3 64 lpm 0.4 mg/m3 >480 minutes Tear Gas (CN) 101 mg/m3 64 lpm 0.3 mg/m3 >480 minutes *These tests are part of the performance specifications for the C2A1 military canister. The PA3NBC Cartridge meets or exceeds the performance requirements of the C2A1 canister for these gases. HE particulate filters are 99.97% effective against all particulate aerosols. Filters and cartridges are supplied in quantities of six per box. The following abbreviations are approved by NIOSH to indicate the particulates, gases or vapors which are removed by the gas/vapor cartridges: CL Chlorine CD Chlorine Dioxide HC Hydrogen Chloride SD Sulfur Dioxide FM Formaldehyde AM Ammonia MA Methylamine OV Organic Vapors HF Hydrogen Fluoride HE High Efficiency Particulate Air Filter for Powered Air-Purifying Respirators www.bullard.com WARNING Use only the cartridge described in the above table. Used/particulate-laden cartridges must be changed as a set and not individually. All cartridges must be of the same type. Do not change cartridges while in a hazardous atmosphere. Incorrect cartridge selection will invalidate all performance statements and approvals for this equipment. Three (3) of the same type of cartridge must be used on the PA3ISBU blower unit, with the exception of the PAPRFC1 filter which are used two (2) at a time, in conjunction with the PA3PG plug. DO NOT use the PA3PG plug to close off a port with any other cartridge type. For Hospital Preparedness applications, the PA3NBC cartridges and PA3BU blower should only be used with the 20SICVH and 20SICV hoods. These hoods are made of Tychem SL, which has been tested by DuPont and shown to be effective against chemical warfare agents. These hoods also feature a press polished vinyl lens adequate for hospital preparedness applications. These respirators are not NIOSH-approved for use against chemical warfare agents. The respirator and cartridges should not be used beyond eight (8) hours after initial exposure to chemical warfare agents to avoid possibility of agent permeation. If liquid exposure is encountered, the respirator should not be used for more than two (2) hours. Follow established cartridge change schedules to ensure that cartridges are replaced before breakthrough occurs. Failure to follow these warnings could result in death or serious injury.
Mounting and Replacing Cartridges on the Blower Unit The useful life of a chemical cartridge for vapors and gases will vary with the concentration and nature of the contaminant, the breathing rate of the respirator wearer, and ambient temperature and humidity. The Occupational Safety and Health Administration (OSHA) regulations 29 CFR 1910.134 require that the employer must implement a change schedule when using Air-Purifying respirators for protection against gases and vapors, if there is no end-of-service-life indicator on the cartridges. The change schedule must be based on objective data that will ensure that the cartridges are replaced before the end of their service life. Factors to consider include workplace conditions such as contaminant concentration, relative humidity, temperature, work activities, respirator use pattern (e.g., continuous or intermittent use), presence of other contaminants, potential for contaminant migration/desorption, health effects of the gas or vapor, and the presence of any warning properties. Contact Bullard for further information on change-out schedules. High efficiency particulate filters must be replaced when retained particles clog the filters and reduce air flow below acceptable levels, as indicated by testing with the Air Flow Indicator. To Replace Cartridges Remove the air-purifying element from its packaging, and inspect for damage. If in doubt do not use. Check that the air-purifying element has not exceeded its “use-by” date and that the connecting thread is in good condition. Check that the air-purifying element is appropriate to the hazard. If in doubt consult your respirator program administrator or supervisor. Check that the threads in the blower unit port are in good condition and clear of contaminant. Check that the PA3ISBU blower ports have the rubber gasket seals present. Remove the air-purifying element seals (see Figure 4). Screw the air-purifying elements into the receptacles (see Figure 5) Figure 4 until the cartridge is hand tight. DO NOT OVER-TIGHTEN. When using the two PAPRFC1 filter cartridges, install the filter plug into one of the ports. DO NOT OVER- TIGHTEN (Figure 6). Figure 6 PA30IS Series Powered Air-Purifying Respirator PA3IS Blower Assembly User Manual Figure 5 www.bullard.com Donning the Blower and Respirator Prepare to don the blower, battery and hood in a safe, hazard-free area and do the following: Check that the cartridges are properly mounted on the blower unit. Prior to assembling the system, place the battery in the battery compartment on the back of the blower. Make sure that the correct battery is used in the appropriate blower unit. (See instructions and warning on page 2). Fit the blower and belt around the user’s waist. With the blower at the rear of the user, adjust the belt for a comfortable fit. Remove the belt and blower. Ensure that the cartridges used are suitable for the contaminant in question and are compatible with the PA3ISBU Blower Unit. WARNING The use of any cartridge not approved with the PA3ISBU blower units may put the user at risk and could result in death or serious injury. Donning the PA3ISBU with the CC20 Series Hood Adjusting and Installing Headband Suspension in Hood NOTE 20LF and 20LF2 series loose-fitting facepiece hoods have a sewn-in headband. NOTE RT Series hoods do not use a suspension. To change the headband size, unlock the four pins from the sizing holes. Place the headband on your head. Pull down, allowing headband to expand until it feels comfortable. The headband will automatically adjust to your size. Lock into place by pushing the four pins into the sizing holes (Figure 7). Figure 7 NOTE If using the optional 20RT ratchet headband suspension, refer to the instruction sheet provided with the 20RT. Adjust Crown Straps for Vertical Fit To improve suspension comfort, adjust crown straps vertically by repositioning the crown strap posts in the crown straps. Vertical adjustment makes the headband ride higher or lower on the wearer’s head. To adjust, push crown strap post from slot, move to new slot, and snap in to secure. Move key to desired vertical position. Repeat for other crown strap post (Figure 8). NOTE Brow pad Figure 8 If the hood rises off your head during use, first verify proper air pressure, then select a different hood for your application, or use the optional chin strap. 8 64 7 63 7 62 7 61 SIZE 7 60 7 59 7 58 7/8 3/4 5/8 1/2 3/8 1/8 Crown strap 7 57 6 56 7/8 6 55 Crown strap post 6 54 6 53 3/4 5/8 1/2 Mounting the Cartridges / Donning the Blower 5
